The InboxGeek system will retrieve all of the contact lists in your Campaigner account. In order for your integration to perform, a list size of at least 30k is recommended. If a list size of under 15k is integrated, it is unlikely to see any results from your integration.
Select the contact list that you’ve created/chosen to use with InboxGeek and click Next.
NOTE: Multiple lists can be chosen for your integration. InboxGeek will filter and suppress duplicate contacts to prevent sending numerous events to a single contact.

InboxGeek will move you to the next tab, Integration.
